FOLDING BED.

Application filed December 13, 1909, Serial No. 532,791.

Specification of Letters Patent.

To all whom it may concern:

Be it known that l, Gnonon FisoHRUPP, a citizen of the United States ofAmerica, and aresident of Chicago, in the county of Cook and State ofIllinois, have invented certain new and useful Improvements in FoldingBeds, of which the following is a specification.

This invention relates to that type of f lding beds in which the bedforming sect'ons are connected together in a longitudinal manner and areadaptedto fold together into a box or housing to provide a seatingfixture for day use. And the present improvement has for its object toprovide a simple and eliicient construction and combination of the bedforming sections, which in an opening movement of the sections toprovide a bed surface, the parts automatically rise and are shiftedlaterally into an elevated plane to the front of the supporting box orhousing, to afiord an extended and roomy bed surface, and which in aclosin movement of the sections to'provide a seating surface, the partsautomatically descend and move back laterally into the supporting box orhousing, all as will hereinafter more fullv appear.

In the accompanying drawings: Figure 1, is a transverse sectionalelevation, illustrating the present invention applied to a box couchbed, and with the parts in a closed condition. views showing the partsin a partly open and fully open condition, and graphically illustratingthe movement of the parts and their coacting relation. Fig. 5, is adetail plan view of the parts in an open condition.

Similar numerals of reference indicate like parts in the several views.

Referring to the drawings, 1 represents the box or housing to which thebed sections hereinafter described are attached, to be supported andhoused thereby. In the construction shown in the drawings such housingis of the ordinary oblong box form known to the trade as the box couchbed; any other ordinary and suitable form' of housing may however beused, as the present improvement is capable of application to the sofaand like type of folding beds now in general use.

2 is a longitudinal rail provided at its respective ends with shortupright members or links 3, and attached by means of pivot pins 4passing through the lower parts of- Figs. 2, 3 and 4, are similarlateral arms 6 to the upper ends of the aforesaid upright members 3 ofthe rail 2 by suitable pivot bolts or rivets as shown.

7 and 8 are counterpart upper, and lower skeleton frame sections of therectangular form shown, and which are pivotally con nected to theopposite ends of the aforesaid intermediate links 5 by hinge connectionswhich permit of an independent quarter turn between the of folding andunfolding hereinafter described.

The intermediate links 5 and frame sections 7 and 8, above described,constitute a marginal supporting frame to which is attached the usualelastic wire webbing (not shown) usually employed in bed frame tosupport an ordinary mattress. Said marginal frame in its foldedcondition as shown in Fig. 1, forms a space for holding the mattress,etc., as usual in folding beds.

9 are lifting levers pivoted to the end bars of the lower frame section8 aforesaid, with their lower ends having bearing upon bottom rails 1'of the housing 1, while their upper ends are pivotally connected to pullbars 10, now to be described.

10 are pull bars pivotally connected at one end to the lifting levers 9,above described, and at their opposite ends to the aforesaidintermediate links 5 at points adjacent to the points of pivotalattachment of the lower frame section 8 to said links 5.

11 are long radius links pivoted at one end to the end walls of thehousing 1, and at the other end to the intermediate links 5, preferablyat the same point of pivotal connection as the pull rod 10 to saidintermediate links 5.

The operation of the parts is as follows: With the parts in the closedor seat condition illustrated in Fig' 1, the operator first tilts backthe cover portion of the box or housing 1, after which an upward pull ismade upon the free end of the upper frame section 7 to move the sameinto the upright position shown in Fig. 2; such movement taking placewithout any movement of the other parts of the bed frame. The operatorexerts an outward and downward pull parts in their movements indicatedin Fig. 4. During such operationv the intermediate links 5, through theinstrumentality of the pull bars 10, levers 9 and bottom rails 1',raises the rear side of the lower frame section 8 to a plane level withthat of the upper frame section 7 and intermediate links 5 aforesaid.Simultaneously with the above described rising movement of the lowerframe section 8, the radius links 11, during the tilting movement of theintermediate links 5., acts to push the entire bed frame outward into aconvenient position for use as a bed surface. Such outward movement is apivotal one and takes place upon the pivot bolts 4 of the short uprightmembers 3, before described. In a folding movement of the parts back tothe original position shown in Fig. 1, the reverse of the movementsabove described takes place.

The different relative positions of the parts, are serially illustratedin Figs. 1, 2, 3. and 4, 1 of the drawings.

Having thus fully described my said invention what I claim as new anddesire to secure by Letters Patent, is:

1. In a folding bed, the combination of a main ,housing, pivot membersattached to said housing, intermediate links pivotally connected to saidpivot members, counterpart marginal frame members pivoted to therespective ends of said intermediate links, and means intermediate ofsaid links and the housing for imparting an upward movement to the framemembers and'intermediate links in an opening movement of the parts, thesame comprising pull bars, levers and horizontal guiding means on themain housing, substantially as set forth.

2. In a folding bed, the combination of a main housing, pivot membersattached to said housing, intermediate links formed with lateral armsfor pivotal connection with said pivot members, counterpart marginalframe members pivoted to the respectiveends of said intermediate links,and means intermediate of said links and the housing for imparting anupward movement to the frame members and intermediate links in anopening movement of the parts, the same comprislng pull bars, levers andhorizontal guiding means on the main housing, substantially as setforth.

3. In a folding bed, the combination of a main housing, a rail disposedlongitudinally between the end walls of said housing and provided withupright end members, intermediate links formed with lateral arms forpivotal connection with said end members, counterpartmarginal framemembers pivoted to the respective ends of said intermediate links, andmeans intermediate of said links and 'the housing for imparting anupward movement to the frame members and intermediate links in anopening movement of the parts, the same comprising pull bars, levers andhorizontal guiding means onthe main housing, substantially as set forth.

4. In a folding bed, the combination of a main housing, short uprightmembers ivoted at their lower ends to said housing, intermediatelinkspivoted to said upright members, counterpart marginal frame memberspivoted to the respective ends of said intermediate links, and meansintermediate of said links and the housing for imparting an upwardmovement to the frame members and intermediate links in an openingmovement of the parts, the same comprising pull bars, levers andhorizontal guiding means on the main housing, substantially as setforth.

5. In a folding bed, the combination of a main housing, short uprightmembers piw oted at their lower ends to said housing, in-

termediate links formed with lateral arms for pivotal connection withsaid upright members, counterpart marginal frame members pivoted to therespective ends of said intermediate links, and means intermediate ofsaid links and the housing for imparting an upward movement to the framemembers and intermediate links in an opening movement of the parts, thesame comprising pull bars, levers and horizontal guiding means on themain housing, substantially as set forth. I
